A heel-burnishing machine containing the following instrumentalities, viz: a substantially-stationary jack to hold the shoe the heel of which is to beburnished, an oscillating bnrnishing-tool, its carrying-arm, the block upon which the said arm is pivoted, and the oscillating shaft upon which the said block is fitted to slide longitudinally and to oscillate therewith, combined with a lever or arm to engagea part of the said block and move the same longitudinally upon the said shaft during its oscillation, whereby the burnishingtool during the oscillations of the shaft is made to travel from the tread end to the heelseat. end of the heel, substantially as described.

2. In a heel-burnishing machine, the following instrumentalities, viz: an oscillating shaft, a block splined thereon and made longitudinally movable with relation to the said shaft, a tool-carrying arm c, carried by the said block and provided with an arm or projection 15,1iaving' a cam-surface, connections to move the said arm or projection, and a jack restrained from vibration in the direction of the length of the said oscillating shaft and having a roller or other stud, the parts being united to operate substantially as described, whereby as the burnishing-tool is made to travel from the tread end of the heel to the seat end, and vice versa, the jack islowered and raised as required, substantially as de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
